The effect of quercetin on bone healing in an experimental rat model
Abstract
Objectives This study aims to evaluate the effect of quercetin on fracture healing in an open fracture model in rats. Materials and methods A total of 80 Wistar-Albino male rats were used in this study. The rats were divided into 10 groups. Daily oral treatment of 100 mg/kg of quercetin dissolved in corn oil were given to four groups, whereas the other four group of control rats were treated with corn oil only. Histopathological and radiological examinations of fracture healing were performed at the end of Weeks 2 and 4 in these rats, while biomechanical and biochemical examinations were performed at the end of Weeks 4 and 6, since harder callus was required. Among the rats in the last two group that were not subjected to the open fracture model, one group was given only quercetin for three weeks and the other for six weeks, and the biochemical markers in the blood were compared between these two groups. Computed tomography images were taken for radiological evaluation. The modified Lane and Sandhu scoring system was used for histological evaluation. The 3-point bending test was performed for biomechanical evaluation. For biochemical evaluation, plasma alkaline phosphatase (ALP), acid phosphatase (AP), total antioxidant status (TAS) and total oxidant status (TOS) levels were measured. Results Radiologically, there was no significant difference between the early-stage results of quercetin and control groups (p=0.247), while quercetin caused a significant increase in callus…
